Suppose you have a triangle whose vertices are A, B and C, and the sides opposite these vertices are a, b and c, respectively. Cut out the triangle. Fold it so that vertex B meets vertex C. Mark the point where this fold is on side a. Mark this point as D and fold along AD. Fold it so that vertex A meets vertex C. Mark the point where this fold is on side b. Mark this point as E and fold along BE. Fold it so that vertex A meets vertex B. Mark the point where this fold is on side c. Mark this point as F and fold along CF. The three folds, AD, BE and CF meet at the circumcentre. You do not need all three - any two of them will do.
A triangle with two lines of symmetry does not exist. It can have one line of symmetry (an isosceles triangle) or three (an equilateral triangle), but not two.
There are no inequalities when it comes to addition and subtraction. Both formulas are designed to secure precise and concise equations. This goes for positive numbers, along with negative numbers.
A magic triangle is a numerical arrangement similar to a magic square, where numbers are placed in a triangular format instead of a square grid. In a magic triangle, the sums of the numbers along each side of the triangle and sometimes along certain diagonals are equal to a constant known as the magic constant. While magic squares typically feature rows and columns, magic triangles focus on the triangular configuration and its properties. Both concepts are part of recreational mathematics and explore the relationships between numbers in unique ways.
A triangle with angles measuring 103°, 20°, and 57° is classified as an obtuse triangle because one of its angles (103°) is greater than 90°. The sum of the angles in any triangle is always 180°, and in this case, 103° + 20° + 57° equals 180°. Thus, the triangle is valid and has one obtuse angle along with two acute angles (20° and 57°).
In QBasic graphics, you can fill a triangle using the PUT statement along with the LINE statement to draw the triangle's outline, and then use the FILL statement to fill the interior. First, define the triangle's vertices by specifying their coordinates, then use LINE to connect these points. After outlining the triangle, you can use the FILL statement to fill it with a specified color. Make sure you have the graphics mode set up properly using SCREEN before drawing.
Use the information you're given and didn't mention in the question, along with all the formulas and equations you know that talk about the relationship among parts of triangles, to calculate the unknown numbers from the known numbers.
The numbers 1-9 sum to 45. If they are to be sum to 15 on each of three sides of a triangle, no number can be counted more than once (15*3 = 45). That is, there are no numbers at any of the vertices. Then there are several possible options: 1, 5, 9 along one side, 2, 6, 7 along the second 3, 4, 8 along the third. So, if x marks the vertices . . . . .x . . . .1 . 2 . . .5 . . . 6 . . 9 . . . . . 7 . x . 3 4 8 . x
A triangle has three vertices. Each vertex is a point where two sides of the triangle meet. In total, a triangle is defined by these three vertices, along with its three sides.
A 30-60-90 right triangle
Pythagoras's Rule does not work if the triangle is not a right angle triangle, that is having one angle equal to 90 degrees. (The rule can still be applied by creating right angles along one or more sides, using lines perpendicular to the side.)

The probability theory was his contribution, along with the Pascal's triangle.
